:atented April 9, 1907.

Application filed August 6,1906. Serial No. 329,385.

To all whom, it may concern:

Be it known that I, GODFREY J. KAPLAN,

a citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in a Combined Churn and Butterorker; and I do hereby de clare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has for its object to provide a simple and efficient combined churn and butter-worker; and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 shows the improved machine in side elevation. Fig. 2 is a transverse vertical section taken on the line of Fig. 1, and Fig. 3 shows the machine in end elevation with some parts sectioned on the line a 90 of Fig. 1 and some parts broken away.

The numeral 1 indicates a horizontallydisposed rotary drum having rigidly-secured heads, which heads are provided with projecting trunnions 2, that are journaled in bearing-brackets 3, rigidly secured to the floor or other suitable support.

Rigidly secured within the drum and extending axially thereof from one head to the other is a centrally-disposed abutment l, which in the preferred arrangement of the machine is square in cross-section, as shown in Fig. 2.

Rotatively mounted within the drum for cooperation with the square abutment 4 is a pair of so-called paddle-rollers 5. These paddle-rollers 5 in this preferred construction of the machine are mounted to rotate close to the shell of the drum and are located diametrically opposite to each other, their arms being arranged in a common plane, which plane intersects also the axis of the drum and two of the projecting angular cor- 11ers of the square abutment 4. The rollers 5 are provided with projecting shafts or trunnions at one end that extend through the adjacent head of the drum and are provided 1 with sprockets 6. Loosely mounted on that trunnion 2 that is at the same end of the drum as the sprockl ets 6 is a relatively large sprocket 7. A second sprocket S is also loosely mounted on the said trunnion, and the said two sprockets 7 and S are secured to a common hub or sleeve so that they are mounted for common rotation.

A counter-shaft 9 is mounted to rotate in suitable bearings on onoto wit, as shown, the rigl1t-handbracket 3 and is provided at its inner end with a spur-pinion 10, that meshes with an internal ring-gear 11, secured on the adjacent head of the drum. At its outer end the shaft 9 is provided with a rigidlysccured pulley l2 and with aloose pulley 13, over which a power-driven belt (not shown) will run. 011 the counter-shaft 9 is also a sprocket 1%, that alines with the sprocket 8. A sprocket-chain 15 runs over the sprockets 14 and S, and a sprocket-chain 16 runs over the sprocket 7 and over the roller-sprockets 6.

The drum 1 is, as shown, provided with door-openings that are normally closed by the usual door devices 17.

The operation of the improved machine is substantially as follows: By means of the driving connections described the two paddle-rollers 5 and the drum will be rotated on their own axes in the same direction; but said rollers will be rotated at a much higher rate of speed than said drum. In the churning action the paddle-rollers act to a very great extent as lifting-flights to lift the cream and drop the same onto the central abutment 4t, and they also produce by their own rotations a continuous paddling action which subjects the cream to a rapid succession of concussions, thereby greatly assisting in the churning action. To illustrate the butter-working action of the machine, we will assume that the drum is being driven in the direction of the arrow marked thereon in Fig. 3, in which case the paddle-rollers will be driven in the direction of the arrows marked adj accnt thereto in the said view. It is evident that the paddleroller 5, which is moved upward on the rising side of the drum, will act to lift the body of butter which was previously at the bottom l l l l l of the drum, and all the while that it is lifting the butter it will act to cut portions from the main body of the butter and force the same against the inclined adjacent surface of the abutment 4, and thence downward through the space between the said abutment and the said roller. The two paddle-rollers, as is evident, will be brought into action in succession, so that the butter-working action is continuous. If Fig. 2 be turned upside down, it will be seen that the roller which was previously on the downward-moving side of the drum is then on the rising side of the drum and cooperates with the central abutment 4 in exactly the same manner that the other roller did when it was moving upward on the rising side of the drum, as just above described.

The rollers, it will be noted, are so located that their own axes lie in radial planes that intersect the axis of the drum and the adj a cent angular corner of the relatively fixed abutment 4, so that the inclined surfaces of the said abutment, together with the cooperating rollers, form hopper-like receptacles which receive the body of butter on the rising side of the drum, and thus facilitate the working of butter between the said rollers and fixed abutment.

The machine would be operative with but one paddle-roller, but would not be very efficient because the butter would be worked only about one-half of the time with each rotation of the drum. On the other hand, three paddle-rollers might be employed, in which case it will be advisable to make the fixed abutment triangular in cross-section.

The driving mechanism described is a single-speed drivethat is, is arranged to im part the same speed of rotation to the drum and rollers both in the churning and butterworking actions. The internal mechanism of the churnto wit, the cooperating roller and abutments is, however, independent of the specific character of the driving mechanism; but the paddle-rollers should nevertheless be rotated on their own axes in the same direction as the rotation of the drum, and they should be driven at a relatively high rate of speed.

The churn described can be constructed at very small cost and, furthermore, is efficient both in the churning and butter-working actions.

lVhat I claim is- 1. The combination with a horizontallydisposed rotary drum having an axially-disposed abutment, of a paddle-roller mounted within said drum between said abutment and the peripheral shell thereof, and means for rotating said drum and roller in the same directions, substantially as described.

2. The combination with a horizontallydisposed rotary drum having a fixed central abutment, of a paddle-roller mounted within said drum between said abutment and the peripheral shell of the drum, and means for rotating said drum and said roller in the same direction, the latter at a relatively high rate of speed, substantially as described.

3. The combination with a horizontallydisposed rotary drum having an axially-disposed abutment fixed to the heads thereof, and which abutment is angular in crosssection, a paddle-roller mounted to work in said drum parallel with and adjacent to one of the angular projecting edges thereof, and means for rotating said drum and roller in the same directions, substantially as described.

4. The combination with a horizontallydisposed rotary drum having an axially-disposed abutment fixed to the heads thereof, a plurality of paddle-rollers carried by and working within said drum and cooperating in succession with said abutment, and means for rotating said drum and said rollers in the same direction, substantially as described.

5. The combination with a horizontallydisposed rotary drum having fixed to the heads thereof an axially-disposed abutment that is angular in cross-section, a plurality of paddle-rollers carried by and working within said drum, said rollers being located each adjacent to one of the projecting angular edges of said abutment, and means for rotating said drum and said rollers in the same direction, substantially as described.

6. The combination with a horizontallydisposed rotary drum having fixed to the heads thereof an axially-disposed abutment that is approximately square in cross-section,

a pair of paddle-rollers carried by and working within said drum, said paddle-rollers being located diametrically opposite to each other in a plane that intersects the axis of the drum and two of the projecting edges of said. abutment, and means for rotating said drum and said rollers in the same direction, substantially as described.

7. The combination with a horizontallydisposed rotary drum having a central abutment, of a plurality of paddle-rollers carried by and working within said drum and having projecting shafts equipped at their ends with sprockets, a pair of intermediate sprockets mounted on the projected axis of the drum at the exterior thereof, a power-driven sprocket-shaft, having a sprocket and a pinion, a sprocket-chain running over the sprocket of said shaft and over one of said intermediate sprockets, another sprocket-chain running over the other intermediate sprocket and over the roller-sprockets, and a ring-gear carried by said drum and meshing with the pinion of said power-driven shaft, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
